Research Projects

This section focuses on the research projects undertaken by Institute of Health and Sports Science & Medicine, Juntendo University as well as collaborative research projects in which it is involved. This section introduces the content of each project, including research studies that have already been completed.


The Juntendo Fitness Plus Study: J-Fit+Study

In our university, various records pertaining to physical attributes and physical strength have been accumulated for approximately 50 years, and data regarding more than 10,000 alumni and current students have been collected. We consider it our social mission to utilize this data to conduct research studies across a wide range of fields related to health and sports sciences; in this spirit, we have launched the “Juntendo Fitness Plus Study,” or alternatively, “J-Fit+ Study.” The “+” in “J-Fit+” means that more data will be added in the future and that more research studies will be developed by making use of ideas from researchers inside and outside our university. We hope that this research will contribute to society through the promotion of health and sports science research.


Project for athlete

Competitive sports, such as high-power sports, endurance activities, mixed sports, esthetic sports, and fighting, involve various athletic disciplines; physical attributes (body types) and the features of physical strength are known to greatly differ according to the type of athletic discipline, but details regarding this issue are as still not known. If the physical attributes and the features of physical strength in each type of athletic discipline can be determined and if its temporal variations are known, it could allow for clarification of the features of an athlete’s discipline and provide information that is useful for maximizing training effectiveness, conditioning management, transferring to another athletic discipline, or even selecting an appropriate type of athletic discipline.

At the Institute of Health and Sports Science & Medicine, which is affiliated with the Juntendo University Graduate School of Health and Sports Science, we are examining the physical features of athletes involved in various disciplines by conducting various physical fitness tests, blood tests, and nutritional surveys; we are also conducting psychological surveys and genetic surveys on athletes who are professionally engaged in sports competitions, mainly in Juntendo University’s sports clubs and student associations. We intend to conduct a comprehensive verification of the physical features of athletes in each type of athletic discipline, the effects of their training, as well as their relation with competition results. Further, through measurements and tests, we will make sure to objectively determine the physical features of the players themselves, as well as those of the team, and for that purpose, feedback will be given on the basis of the collected data, and advice will also be provided to those who want it. We consider that the mission of this research project is to disseminate accurate information by contributing to the sports-related scientific evidence for each type of athletic discipline.

Further, joint studies conducted based on data from this research project and other on-campus and off-campus projects might also lead to the development of research studies such as those examining the impact of the level of physical strength in each athletic discipline practiced during college years and may also contribute to development of preventive measures against diseases in Japan’s super-aging society.


Branding project

Juntendo University was selected by the Japanese Ministry of Education, Culture, Sports, Science, and Technology for two years in a row (2016 and 2017) for its Private University Research Branding Project. Both Juntendo University’s Faculty of Health and Sports Science and Graduate School of Health and Sports Science play a central role in the following projects.


Children’s physical exercise project

Exercise habits in childhood have been pointed out to be associated with an increased incidence of lifestyle-related diseases in middle-aged and elderly individuals, a decreased independence in daily living activities, and an increased incidence of mental illness.
In this project, our aim was to develop research studies by using various methods, including intervention research, and to establish a methodology that improves children’s physical and mental health through exercise and sports.

(The ‘Establishment of a sports medical science base for promotion of children’s health,’ which was part of the MEXT-Supported Program for the Strategic Research Foundation at Private Universities, started in 2011 and ended in 2015.)


Disclosure of research information (opt-out)

As a general rule, when research is conducted on human subjects, consent should be obtained directly from the prospective participant; however, in some cases, when the research study uses information that has already been obtained, it can be carried out without prior explanation or request for consent. In such cases, the “ethical guidelines for medical research conducted on human subjects” stipulate that when research is carried out after public disclosure of the research contents, including the purpose of the use of medical information in the study, the prospective study participant (including their legal representative) must be guaranteed an opportunity to refuse to participate. This is called an “opt-out” method of consent.

Among the research topics at the Institute of Health and Sports Science & Medicine, “opt-outs” are applicable to the research subjects listed below. If you do not wish to cooperate with the research study, please contact the person in charge of the research, whose name is listed in the following document.

Research topics
